2.4 Kev Ruaj Ntseg

HEMC pab txhawb rau kev ruaj khov ntawm cov khoom sib xyaw, tiv thaiv kev sib cais thiab ua kom muaj kev faib tawm sib npaug. Qhov kev ruaj khov no yog qhov tseem ceeb hauv cov qauv uas tswj kev sib xws yog qhov tseem ceeb, xws li hauv cov tshuaj sib xyaw ua ke.

3. Cov Ntawv Thov Hauv Kev Tsim Kho

3.1 Cov Nplaum Thiab Cov Grout Rau Pobzeb

Hauv cov nplaum thiab cov grouts rau pobzeb, HEMC ua rau kom cov dej khaws cia zoo dua, txhim kho kev nplaum, thiab muab cov viscosity tsim nyog rau kev siv yooj yim. Nws pab txhawb rau kev ua haujlwm tag nrho ntawm cov khoom no.

3.2 Cov Cuab Yeej thiab Cov Qauv

HEMC feem ntau siv rau hauv cov mortar thiab render formulations los txhim kho kev ua haujlwm, tiv thaiv kev sagging, thiab txhim kho kev sib txuas ntawm cov khoom sib xyaw rau cov substrates.

3.3 Cov Tshuaj Sib Xyaws Uas Ua Rau Nws Tus Kheej Sib Npaug

Hauv cov tshuaj sib xyaw ua ke uas nws tus kheej leveling, HEMC pab tswj cov khoom ntws uas xav tau, tiv thaiv kev poob qis, thiab xyuas kom meej tias qhov chaw du thiab tiaj tus.

3.4 Cov Khoom Siv Ua Los Ntawm Cement

HEMC raug ntxiv rau cov khoom siv cement xws li grouts, concrete admixtures, thiab plasters los tswj viscosity, txhim kho kev ua haujlwm, thiab txhim kho kev ua haujlwm tag nrho.

4. Tej Yam Yuav Tsum Xav Txog Thiab Yuav Tsum Ceev Faj

4.1 Kev Siv Tshuaj thiab Kev Sib Piv

Qhov ntau npaum li cas ntawm HEMC hauv cov qauv tsim kho yuav tsum tau tswj hwm kom zoo kom ua tiav cov khoom xav tau yam tsis muaj kev cuam tshuam tsis zoo rau lwm yam ntxwv. Kev sib raug zoo nrog lwm cov khoom ntxiv thiab cov ntaub ntawv kuj tseem ceeb heev.

4.2 Kev Cuam Tshuam Ib Puag Ncig

Thaum xaiv cov tshuaj ntxiv rau kev tsim kho, suav nrog HEMC, yuav tsum xav txog lawv qhov cuam tshuam rau ib puag ncig. Cov kev xaiv uas ruaj khov thiab zoo rau ib puag ncig yog qhov tseem ceeb zuj zus hauv kev lag luam kev tsim kho.

4.3 Cov Lus Qhia Txog Khoom

Cov khoom HEMC yuav txawv ntawm cov lus qhia, thiab nws yog ib qho tseem ceeb uas yuav tsum xaiv qib tsim nyog raws li cov kev cai tshwj xeeb ntawm daim ntawv thov kev tsim kho.
